A number of tests on older men with nocturia have indicated that taking desmopressin helps to alleviate some of the symptoms.
Nocturia, or frequent nighttime urination, affects a significant amount of elderly men and can be uncomfortable and stressful, leading to lack of sleep and sometimes depression.
Connected with obstruction of the prostate gland, the problem can be hard to control and many medications, including some alpha-blockers, fail to make a noticeable difference.
However, a study carried out on 28 men in Taiwan found that the number of urination trips in men who took the desmopressin decreased from 6.1 to 3.5, reports Reuters.
Most effective in those with severe nocturia, the drug was found to be successful in 24 of the older men.
The authors of the study said that it was effective in "patients with nocturia and decreased nocturnal functional bladder capacity" but added that those with nocturnal polyuria, a slightly different condition, would not benefit from the treatment.
"We need to recognise this drug's safety and correct application," commented Dr. Chih-Shou Chen from Chang Gung Memorial Hospital, adding that more research was needed.
